A cam lock connected with a fence assembly includes a handle portion, a top carrier and a bottom carrier connected by a threaded shaft. The handle portion and top carrier are positioned above the fence assembly and a work table or surface; wherein the bottom carrier is positioned below the fence assembly and work table or surface. The top carrier and bottom carrier both have a pair of alignment arms with a space positioned therebetween, the alignment arms of the top carrier nest with the alignment arms of the bottom carrier. The handle portion and top carrier both have cam surfaces that engage one another such that when the handle portion is rotated around the axis of the threaded shaft the handle portion is raised or lowered thereby raising or lowering the bottom carrier, thereby locking or unlocking the fence assembly in a quick, durable, easy and accurate manner.

The invention relates to a device (21) and to a method for processing a rim (1) for a vehicle, in particular an automobile or truck, said device comprising means (2) for supporting the rim, means (3) for centering the rim, and means (4) for drilling, wherein the means for supporting the rim have a protective insert (5), in particular a funnel-shaped element, and can be inserted into an inside (6) of the rim, wherein the rim is arranged on the means for support with the inside in a direction (7) downward and is retained laterally by the means of centering, in particular two means for centering that are arranged opposite, wherein the rim should be oriented with a central wheel hub axis (8) substantially concentric with respect to a processing axis (9) of the means for support, wherein in a wheel hub region (10) the wheel hub region can be drilled into through the means for support from a direction (11) of the inside of the rim by means of the means for drilling.

A wheel bolt hole chamfer device is composed of a base, a support frame, a lower servo motor, a turntable, stop blocks, guide rails, strong springs, a driving friction wheel, driven shafts, driven friction wheels, chamfer cutters and the like. The device can be put into a production line as a fourth-procedure machining device, and bolt hole chamfers are no longer machined in three procedures, so that the three-procedure machining time is reduced; and after the fourth procedure for machining the bolt hole chamfers is supplemented, the machining time of a single wheel is shortened, and the efficiency is improved. The device integrates pitch diameter adjustment and rotating drive of the chamfer cutters, so that a drive system and a power system are greatly simplified, i.e., the manufacturing cost of the device is reduced, all bolt hole chamfers can be machined at the same time.

The present disclosure belongs to the technical field of tools for bridge reinforcement, and particularly relates to a precisely-positioned drilling apparatus for steel tubular joints. According to the present disclosure, a lifting frame unit, an electric drill, a lever unit, a positioning tube unit, and a diagonal tensioning member unit are arranged on a base unit such that 1. during drilling, a drill rod is not prone to deviation, and a drilling action is relatively precise, resulting in an approximately circular shape of a final drilled hole; and 2. the above lever unit is essentially a labor-saving lever that ensures relatively easy and convenient drilling operations. Additionally, the present disclosure further discloses an application method of the apparatus, which ensures that the apparatus may stably fit with and be safely available for electric drills with various sizes and specifications.

A pocket hole drilling machine is presented. The pocket hole drilling machine has a cabinet made of a molded unitary monolithic piece. A monolithic top plate is connected to the cabinet with an opening in the middle for an insert plate which is positioned therein. A handle extends above the top plated as does a clamping assembly however actuating mechanics of the device move within the cabinet, thereby improving safety by eliminating pinchpoints. An adjustable fence assembly having cam locks connected thereto is also connected to the top plate. This arrangement provides a low cost, safe and efficient pocket hole drilling machine.
